Did IB 6 actually get released? My own memory has IB 6 in beta when Inprise open-sourced the entire thing... IB 6 was finally released but only sometime after Firebird project was started in 2000 and Inprise changed their mind about the whole open-source thing. > More currently, the FirebirdSQL website ( http://firebirdsql.org/manual/isql- > dialects.html ) says: > > "Currently it is possible to create databases in Dialect 1 and 3 only, > however it > is recommended that you use Dialect 3 exclusively, since Dialect 1 will > eventually be deprecated.

[the highlighting > is mine] In our case, having started using IB v4.x, we have been locked-in to dialect 1 and we are using v2.5 (looking at v3.x). The most significant issue with dialect 3 is the "stupid" interpretation that Inprise made of the SQL standard when it comes for handling of precision in math operations -- our application had way too many processes that expected the dialect 1 handling/treatment that the cost of "re-tooling" and testing was much too high. IMO, the dialect 3 math precision handling is so bad, that if I had to make a fresh choice today, I would still choose dialect 1. So, personally, I don't blame anyone for making the same choice. We are hoping that Firebird will adopt more "logical/appropriate" rules for dialect 3, there has been talk of same. Until then, we will keep using dialect 1 for as long as possible. Sean
